Good speakers, have been working great so far combined with our Behringer mixer/amp. They've got plenty of power and headroom available, and enough bass even to amplify some drums etc.
They're very heavy though, need two people to move, so keep this in mind if you're considering these for your band for live shows etc and are going to move them frequently, maybe you don't actually need something this large.
Given their size and weight, they don't have any stand attachment at the bottom, they're more intended to be left on the ground, in fact they have some small feet at the bottom. You can always put them on a pair of stools or something, that's what we did, just be sure they're sturdy enough, like I said these speakers are heavy.
